To all whom, t may concern: i

y Beit known that we,W1LLIAM D. BALDWIN, residing in the city and county of NewYork,

v and AUGUST SUNDH, residing at Yonkers, in 5 the county of Westchester, State of New York, citizens of the United States, have invented certain new and usefullmprovements in Shiftf ing Devices for Piers, dac., of which the fol-l lowing is a specification. 1o l Our invention has for its object to provide a ready means of securing any desired draft at any required speedof motion `upon a cable leading to an object to be moved or raised or lowered adjacent to'anembankmentor pier;

- r 5 and our invention consists in providing a capstan arranged at any suitable point above the footway of such embankment or pier with means below said footway for actuating the capstan, as fully set forth hereinafter and as 2o illustrated in the accompanying drawings, in

whichi Figure l is a sectional elevation of a part, of

a pier or embankment with a capstan and 0p'- erating and controlling means embodying our 2 5 invention.

tion, part of the'top being broken away to exf pose the apparatus below the footwayyand.`

Fig. 3 is a sectional view illustrating 'part of the driving-gear of theapparatus. 3o A represents the pavement or footway of a pier or embankment adjacent to which vessels-or barges may be brought for the purposel of loading or vunloading,and B representsa capstan which is arranged in such position 3 5 upon the said footway or pier that cables C lcan be carriedV with facility from thevessel or tackle of thevessel to the capstan, and in connection with the latter we provide a'motor f and means whereby the vsame* may be set in 4o operation to Arotate :the capstan at different speeds'or in different directions, so that it is l necessary for the operator simply to lap the cable one or moretimes around the capstan in the proper directionand to then start thel A4|; motor in operation to raiseor lower loads which otherwisewould require a number of persons to handle or the use of a portable engine. I.

Various differentarrangements of mechan- Fig. 2 is ajplan view in part sec supported upon roller-bearings 13,k turning 95"" ism and dierent kindsof motors and stop- 5o pingjand starting devices may be employed. In the construction illustrated thereis a Ino-` `tor M, which is an electric motor having the u'sual switch within a casing D, controlled by rocking' a shaft 1, provided with a.lever 2, 55'

the current being reversed according as the lever is rocked from a central position in one direction or the other, as is usual in connectionwith electrically-driven machines. In

the construction shown'the shaft 3 of the mo-` 6o l tor extends into a worm-casinget and carries a worin-5, dott-ed lines, Fig..2, which gears with apinion upon a'shaft 7, on .which the capstan B is mounted. The motor audits -adju'ncts are all arranged within a vault or 6 5l pavement A', and there bolted'to any suitable foundation.

It is desirable not only to be able to stop,` v start, and regulatethedirection of movementi y of the capstan, but also to be able to do so 8o v from diierent positiohs,'because the operator` v- 'jmay sometimes require to be upon one sidef of the capstan and sometimes lina dierent Y position, and we therefore provide astopping and starting device which may beN moved from 85 f l "i di'erent points.` This stopping and start-1 ing device may be'constructed in different ways; butas shown it consists' o f'alframe'orvv spider F, mounted tov swingjfreely upon theL y 1 shaft 7 as a center and havingnupwardly-pro- 9o t j e'cting lugs 10, extending through'lslots 1.2 in

the cap-plate 9 andfprojectingfslightly above the surface of said cap`plate,fsofthat the foot may be applied to said lugs-..- This spider is upon studs projecting from standards'14,'ex tending between the bed-plate andcap'.r Th A spider is connected in *t an 'suitable' nner with the control-lever 2. As shown, the spider carries a wrist-pin 15, from which a connecting-rod 16 extends and is jointed to the upper end of the lever` 2, so that whichever of the lugs 10 is moved the spider may be swung so as to impart motion to the lever 2. Said lugs 10 each normally occupy a position between the ends of the slots or openings 12, so that by moving the lug in one direction from the centerI the machine may be started in one direction, while the reverse movement will start the machine in the opposite direction.

The machine is provided at one end with an ordinary braking device J, having a lever 17, which may be vibrated in either direction to lift the brake, and this lever is connected by a rod 18 with the lower end of the lever 2, so that when the latter is swung in either direction to start the motor the brake will be lifted, while when the lever 2 is brought to a central position to stop the motor the brake will be applied, all as in motor apparatus in common use and shown and described in Patent No. 558,075 of April 14, 1896, and therefore not requiring detailed description.

It will be evident that by providing a capstan arranged above the pavement or footway of an embankment or pier with means whereby power may be applied thereto to rotate it in either direction at dierent speeds, starting and stopping the same by the application of the foot when the operator is in different positions, it is possible to manipulate heavy cables for raising and lowering heavy weights or for dragging barges or other vessels to position in a manner which cannot be employed where hand labor or portable engines are used. It will also be seen that the apparatus is fully covered up and protected, so that it may be operated during all kinds of weather and without in any way obstructing the pier or other place in connection with which it is used.

While we have described our invention as used in connection with a capstan arranged upon a pier or embankment, it will be evident that some of the features above described may be used in connection with capstans used on ships or elsewhere.

Without limiting ourselves to the precise construction and arrangement of parts shown, we claim as our inventionl. The combination with the footway of a pier or embankment, of a capstan connected with a shaft extending downward through said footway, a motor connected to operate said shaft and provided with a control device for stopping, starting, and reversing the motor, and a stopping and starting device having projections extending upward through the footway in dierent positions, substantially as and for the purpose set forth.

2. The combination with the footway of a pier or embankment, of a capstan arranged above the footway, a shaft connected to the capstan extending below the footway, a Inotor connected to rotate said shaft and proh vided with stopping, starting, and reversing means, and a stopping and starting device ar :ranged to be actuated by the foot of the operator upon the footway, substantially as and for the purpose set forth.

In testimony whereof we have signed our names to this specification iu the presence of two subscribing witnesses.
